“Unidirectional diodes like the SP1053 and SP1054 Series should always be the preferred solution for protecting I/O and power ports from ESD damage because the content on these lines is unipolar,” said Tim Micun, Business Development Manager, TVS Diode Arrays (SPA® Diodes) at Littelfuse. “Unlike other devices with this footprint, which are either bare silicon or bare silicon covered by an oxide, the SP1053 and SP1054 Series’ hermetically sealed plastic packages protect them against abrasion, temperature cycling and moisture.”

SP1053 and SP1054 Series TVS Diode Arrays offer these key benefits:

The combination of plastic packaging and a compact, 01005 footprint is a market first for protection devices and prevents solder shorts between the terminals, abrasion and moisture intrusion that could interfere with ESD protection.

These unidirectional TVS diode arrays have just half the dynamic resistance of bidirectional solutions, protecting sensitive ports faster and better.

The ultra-small 01005 DFN hermetically sealed package offers a new choice to circuit designers who have been challenged by competing smaller-format end products.
